Question

我是android开发的初学者。我正在尝试创建一个SMS调度程序app.My app的广播接收器的onReceive（）方法没有被调用？下面给出的是我的源代码。我查了一些其他的链接，比如Basic Android alarm app, Broadcast Receiver's onReceive() method not being called请，我想知道我哪里出错了。谢谢。

Homepage.java

    public class Homepage extends Activity
    {
     public EditText get_number;
    public EditText text_box;
    public String search_string,text_box_buffer;
    public Bundle bundle;
    public Intent mesg_intent;
    public PendingIntent pending_intent;
    public AlarmManager alarmManager;
    TimePickerFragment newFragment = new TimePickerFragment();

    public void showTimePicker(View view)
    {
        newFragment.show(getFragmentManager(),"timepicker");
    }

    public void messageSave(View view)
    {
        search_string=get_number.getText().toString();
        text_box_buffer=text_box.getText().toString();
        bundle.putCharSequence("number",search_string);
        bundle.putCharSequence("message", text_box_buffer);
        mesg_intent.putExtras(bundle);
        pending_intent = PendingIntent.getService(this,0,mesg_intent,0);
        alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
        alarmManager.set(AlarmManager.RTC_WAKEUP,newFragment.getTime(),pending_intent);
        Toast.makeText(this,"SMS scheduled to be sent",Toast.LENGTH_SHORT).show();
    }


    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_homepage);
        get_number = (EditText) findViewById(R.id.contacts_search);
        text_box = (EditText) findViewById(R.id.text_box);
        bundle = new Bundle();
        mesg_intent = new Intent(this,Alarmservice.class);

    }


    @Override
    public boolean onOptionsItemSelected(MenuItem item)
    {

        int id = item.getItemId();
        if (id == R.id.action_settings)
        {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

}

TimepickerFragment.java

public class TimePickerFragment extends DialogFragment implements TimePickerDialog.OnTimeSetListener

{ public Calendar c = Calendar.getInstance（）; public int hour = c.get（Calendar.HOUR_OF_DAY）; public int minute = c.get（Calendar.MINUTE）;

@Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
    return new TimePickerDialog(getActivity(),this,hour,minute,DateFormat.is24HourFormat(getActivity()));
}

public void onTimeSet(TimePicker view, int hourOfDay, int minuteset)
{
    hour=hourOfDay;
    minute=minuteset;
}
public long getTime()
{
    long time_ret = new GregorianCalendar().getTimeInMillis()+((hour*60*60*1000)+(minute*60*1000));
    return time_ret;
}

}

Alarmservice.java

public class Alarmservice extends BroadcastReceiver
{
@Override
public void onReceive(Context context,Intent intent_local)
{
    try {
        Bundle received_bundle = intent_local.getExtras();
        String number = (String) received_bundle.getCharSequence("number");
        String message = (String) received_bundle.getCharSequence("message");
        SmsManager smsManager = SmsManager.getDefault();
        smsManager.sendTextMessage(number, null, message, null, null);
        Toast.makeText(context,"SMS successfully sent",Toast.LENGTH_SHORT).show();
    }
    catch (Exception e)
    {
        Toast.makeText(context,"SMS failed",Toast.LENGTH_SHORT).show();
    }
}

}

的Manifest.xml

<uses-sdk
    android:minSdkVersion="16"
    android:targetSdkVersion="24" />

<uses-permission android:name="android.permission.SEND_SMS"/>
<uses-permission android:name="com.android.alarm.permission.SET_ALARM"/>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".Homepage"
        android:label="@string/app_name"
        android:screenOrientation="sensor" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <receiver
        android:process=":remote"
        android:name=".Alarmservice"/>
</application>

问题在于创建意图，请执行以下操作：

mesg_intent = new Intent(this, Alarmservice.class);
mest_intent.putExtras(bundle);
pending_intent = PendingIntent.getBroadcast(this, 0, mesg_intent, PendingIntent.FLAG_UPDATE_CURRENT);

为什么没有调用广播接收器的onreceive（）方法？
